does this have anything to do with EFI boot ?

I don't think this is related to EFI (although I could be wrong). To me it
looks like the driver doesn't currently have the appropriate firmware for
your GPU - although looking at the source i do see references for the Topaz
GPU in the source in:

drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c

mmacy@ may be able to shed additional light on this though.

btw - what git revision are you running?

Cheers,
-pete

@rut78HR is this maybe a dual-GPU notebook (i.e., APU + GPU)? IIRC, we've seen similar issues with those. In general, amdgpu is not yet fully functional (it works well with modesetting, 2D only) and radeon is completely untested.

It is toshiba L-50B-27N serie notebook. Intel broadwell + radeon R7 M260

[mattmacy]

you currently have to disable efifb in order for amdgpu to work on APUs
